Foundation piling system

Abstract

A foundation piling system in which pilings are used to support a foundation system in soil having a varied composition and moisture content. The pilings extend into concrete grade beams forming a portion of a monolithic system including a concrete slab. Flanges extend from the end portions of the pilings that are disposed in the grade beam and a plurality of horizontally extending reinforcing bars extend through openings in the flanges.

What is claimed is: 
     
       1. A foundation system for a building, comprising a plurality of piling members extending into the ground and having a portion projecting from the ground, two flanges extending from diametrically opposite portions of the projecting portion of each of said piling members, each flange having at least two openings extending therethrough, four horizontally extending bar members respectively extending through said openings, said bar members being formed in two spaced rows of two bar members per row, said rows being spaced horizontally and the bar members of each row being spaced vertically, a substantially U-shaped stirrup bar extending around said bar members and within said grade beam, and a concrete structure extending over said projecting portions of said piling members said stirrups and said bar members. 
     
     
       2. The foundation system of claim 1 wherein said concrete structure comprises a slab and grade beam extending around the margins of said slab and having a height greater than that of said slab for supporting the walls of said building. 
     
     
       3. The foundation system of claim 2 wherein said grade beam is integral with said slab. 
     
     
       4. The foundation system of claim 2 wherein each bar member extends throughout said grade system. 
     
     
       5. The foundation system of claim 2 wherein each bar member is formed into a rectangular configuration. 
     
     
       6. The foundation system of claim 1 further comprising a pair of horizontally extending dowels extending from said stirrup bar and within said grade beam. 
     
     
       7. A foundation system for a building, comprising a plurality of piling members extending into the ground and having a portion projecting from the ground, a sleeve extending over and connected to the projecting portion of each of said piling member, at least one flange extending from said sleeve, said flange having at least one opening extending therethrough, at least one horizontally extending bar member extending through said openings, and a concrete structure extending over said projecting portion of said piling members, said sleeve, and said bar member. 
     
     
       8. The foundation system of claim 7 wherein there are two flanges extending from diametrically opposite portions of said sleeve. 
     
     
       9. The foundation system of claim 8 wherein there are two openings extending through each of said flanges, and wherein four bars members extend through the respective aligned openings of said flanges. 
     
     
       10. The foundation system of claim 7 wherein said concrete structure comprises a slab and grade beam extending around the margins of said slab and having a height greater than that of said slab for supporting the walls of said building. 
     
     
       11. The foundation system of claim 10 wherein said grade beam is integral with said slab. 
     
     
       12. The foundation system of claim 10 wherein each bar member extends throughout said grade system. 
     
     
       13. The foundation system of claim 10 wherein each bar member is formed into a rectangular configuration.
